– orange pi zero all have 2 SPI bus: one in the main GPIO port, and one for the flash on the back side. If you don’t have the plus model, you can unsolder the FLASH and use the port. FLASH is port 1, so, GPIO is port 1. This is very important when you follow tutorials written for other opis

– before you start following a tutorial, you need to understand which kernel you are using. If the turial is written after jan 2017, and mentions adding an overlay in armbianEnv.txt, then it’s for kernel 4; if the tuto is before feb 2018, and does not mention altering armbianEnv.txt for SPI compatibility, author is using kernel 3. This is critical.

Raspberry Pi pHAT layout - designed to exactly fit the Raspberry Pi Zero and Zero W. For use with Raspberry Pi A+, B+, 2B, 3B, 3B+, 4B, we recommend our PiJuice HAT module (although, PiJuice Zero will still work with these boards).

Bring your own battery - this pHAT does not come with a battery. We recommend a 2000mAh single cell LiPo with an NTC temperature sensor. When paired with our mating cable it is easy to use any battery with your PiJuice with simple crimp connectors.

Ultimate integrated power is one thing but what if we could make the Raspberry Pi renewably powered too? Solar, wind, thermoelectric and other renewable power is free, clean, and green and we"re proud to have developed an affordable and efficient renewable power solution for the Raspberry Pi! PiJuiceZero is self-monitoring and, like a space satellite, can become a completely autonomous system. Use the PiJuice Zero as part of an autonomous camera system, weather stations, off-grid desktops, and so many other great outdoor projects. View and buy the PiJuice solar panels separatelyhere.

Perhaps you need a huuuuge battery to keep your remote project running, or maybe just a tiny one for a cute wearable project. Either way, we"ve got you covered. PiJuice Zero takes any single cell LiPo. View our available batteries for PiJuice Zero below:

With PiJuice we want to provide not only the best portable hardware/software solution, but also a set of inspiring and affordable guided projects for fun and learning in the real world.

※Price Increase NotificationThe TFT glass cell makers such as Tianma,Hanstar,BOE,Innolux has reduced or stopped the production of small and medium-sized tft glass cell from August-2020 due to the low profit and focus on the size of LCD TV,Tablet PC and Smart Phone .It results the glass cell price in the market is extremely high,and the same situation happens in IC industry.We deeply regret that rapidly rising costs for glass cell and controller IC necessitate our raising the price of tft display.We have made every attempt to avoid the increase, we could accept no profit from the beginning,but the price is going up frequently ,we"re now losing a lot of money. We have no choice if we want to survive. There is no certain answer for when the price would go back to the normal.We guess it will take at least 6 months until these glass cell and semiconductor manufacturing companies recover the production schedule. (Mar-03-2021)

All the accessories listed below tier pricing need to pay.We won"t deliver until you select. Power adaptor should be 5V/2000mA in output and center pin for positive voltage and the outer shield for negative voltage .The temperature for controller RTD2660 would increase during working.That"s normal phenomenon,not quality problem.

It"s also ideal for Raspberry PI by HDMI.

Orange Pi has released the Zero2, a small form factor SBC based on the Allwinner H616 64-bit system on chip (SoC). Capable of supporting Android 10 natively, it contains a quad-core Cortex-A53 processor with integrated Mali G31 graphics. Connectivity is available via Wi-Fi, Bluetooth, and Ethernet, and the Zero2 supports a range of video decoding options up to 4k@60fps.

Compared to Orange Pi Zero, Orange Pi Zero2 offers a 64-bit Arm processor, more RAM up to 1GB, dual-band WiFi, Bluetooth 5.0 (no Bluetooth at all in Pi0), Gigabit Ethernet, and power via a USB-C port instead of a micro USB port.

The touch screen LCD is ready with 320×480 resolution, 50 FPS (Frame per second). Resistive touch control is being supported by the Raspberry Pi OS or Raspbian (directly-pluggable). However, we will still need to install the driver for graphic display :)

However, there is a dedicated case/enclosure and a low-profile heatsink with a fan for this LCD to fit perfectly on the Raspberry Pi 4 Model B. The case has an opening for the LCD, and the low-profile heatsink with a fan keeps the Raspberry Pi 4 Model B protected and cool! You get a perfect console :) Don"t forget to remove the top lid/cover of the enclosure for the 3.5-inch LCD.

Note: The Raspberry Pi 4 Model B, 3.5-inch Enclosure, and the Low-Profile Heatsink with a fan are NOT INCLUDED in this product, please get them separately.

As we understand, Raspberry Pi 4 Model B delivers great performance and of course, more power will generate more heat as of all CPU :) So we need a way to install an additional heatsink to dissipate the extra heat. It will be better if we can have the option to add a cooling fan for active cooling. Well, this 3.5-inch touch screen LCD comes ready with the heatsink and cooling fan for you to use with the Raspberry Pi 4 Model B. it solves all the concerns.

The 3.5-inch touch screen uses the GPIO on the Raspberry Pi board, so it stretches out 2 pins as the power to supply the cooling fan on the low profile heatsink, and keep the Raspberry Pi board cool!

Note: The Raspberry Pi 4 Model B, 3.5-inch Enclosure, and the Low-Profile Heatsink with a fan are NOT INCLUDED in this product, please get them separately.

The Graphic driver is provided and can be downloaded for Raspberry Pi OS/Raspbian. It also supports Ubuntu and Kali Linux. Do follow the steps here: http://www.lcdwiki.com/MHS-3.5inch_RPi_Display

Note: Please use the recommended system for the touch screen. If another system is used, it may not have the touch function or may not work. You need to configure it yourself. Because there are many systems that the Raspberry Pi can use, we can’t make every system compatible with the touch screen.

If the value in the quotations matches EXACTLY Your type of the Orange Pi board, You are probably lucky enough to have a script.bin file that has the correct settings for memory and CPU and You may proceed further to NEXT STEP. Others will need to edit the script.fex file to make it safe.

The numeric value right to the equality sign is the CPU frequency in MHz. If it is below 1000 or only sligtly above (e.g. like 1008) You may leave things as is and proceed further. If otherwise like this example the clock is set to ~1500 or even to ~2000 You better downscale it. Or else make sure that Your board is the really mighty fancy high top end of the orange pi series (like Orange Pi Plus, Orange PI Plus 2, Orange PI Prime, Orange PI Ultimate, Orange PI Unlimited, Orange PI REBIRTH and THE RETURN OF THE ORANGE PI...).

Another place of interest in the script.fex file will be the [dvfs_table] section. You will see the mindscraping table of cpu frequencies there. Here the frequencies are measured in Hz, so you"d like that 9-digit numbers. Once again if Your view is not distorted by very high numbers (like max_freq = 1536000000 and above) of if You have a top end board You can proceed further. Otherwise You should downscale the values. Where to get the correct ones? I suggest to copy-paste them from the: http://www.sunxi.org/Fex_Guide

While googling for any info about lcd controller I came across this page: http://heikki.virekunnas.fi/2015/raspberry-pi-tft/, author managed to get from manufacturer patch file for kernel sources and tested it with 4.1.y - on which lcd worked. But still LCD replace HDMI, but I want to use this screen as additional for user interaction, while the bigger on HDMI as presentation monitor.

Since, fbtft has been merged with rpi kernel, so the fb drivers (including ili9341.c) was moved to fbtft_device driver (so the author of page can"t compile latest kernel with driver+patch).

So something about hardware, which I reverse engineered by the "hard way" - "grab multimeter and run through all LCD FPC pins and shift register pins"

Now I noticed there is "9486L" which can suggest that LCD screen is controlled by ILI9486L, I found this LCD on taobao too but I can"t contact seller.

I"m pretty sure about D/C (Pin 37 on LCD) and Reset (Pin 19 on LCD) pins by looking into driver code, but I can"t identify other signals (WR/RD/CS/etc...)

- Controller is not ILI9341/ILI9325 - those are for smaller displays (320x240, etc...), I guess this might be ILI9486/9488 because they are for 480x320 displays. But when I compared init with DS it does not fit right so LCD can have a clone of ILI9486/9488 ...

- Module use only SPI interface and two CE signals (CE0 for touch controller, CE1 for LCD shift registers - compared to others lcd modules, in KeDei module this is swapped),

In the previous article, I described the steps needed to install an LCD touchscreen on the Raspberry Pi. In this article, I will show you how to adjust the screen rotation of the LCD to landscape mode, and will show you how to calibrate the touchscreen pointer for optimal accuracy. Just follow the steps below to compete the process of setting up your Raspberry Pi LCD touchscreen:

1. First we need to change the setting for screen rotation in the /boot/cmdline.txt file. This setting is called fbtft_device.rotate=X. By default, this is set to X=0, which results in a portrait mode screen orientation. In order to switch the orientation to landscape mode, change fbtft_device.rotate=0 to fbtft_device.rotate=90. Enter sudo nano /boot/cmdline.txt at the command prompt. There should only be one line in this file. Go to the end of it and you will find the fbtft_device.rotate=X setting. Change the value from 0 to 90:

However, if you try to touch the screen now, you will find that the pointer movement does not correspond to your finger movement. This is because the LCD screen driver and the touchscreen controller driver have separate settings for screen rotation. We need to change the rotation of the touchscreen controller driver to match the rotation of the LCD screen driver.

After the Pi finishes rebooting, you should notice that when you move your finger across the touch screen, the pointer should follow correctly in both axes. If you are using the Raspberry Pi 2 Model B, you will need to complete the calibration steps below before the pointer follows your finger correctly (and make sure that you have enabled startx to load automatically – see step 6 in this article).

You can rotate the screen 90 degrees (as we did in this tutorial) and the power connector will be at the bottom of the screen, but you can also rotate it 270 degrees so that the power connector is at the top of the screen. To do this, simply enter fbtft_device.rotate=270 in the /boot/cmdline.txt file. Then change the DISPLAY=:0 xinput --set-prop "ADS7846 Touchscreen" "Evdev Axis Inversion" 0 1 line in the /etc/X11/xinit/xinitrc file to DISPLAY=:0 xinput --set-prop "ADS7846 Touchscreen" "Evdev Axis Inversion" 1 0. All you need to do is switch the values of the 0 and 1 at the end of this line.

Now that we have our LCD touchscreen up and running, the final step in the installation is the calibration of touch control. This will make the pointer much more accurate and easier to use.

This is kind of a long process, but it is well worth it if you want to get the LCD touchscreen set up properly. So if you have any trouble setting this up or have anything to say, please leave a comment below. Also, if you found this article useful, please share it with your friends!
